My pit runs with the band when they do laps. And they have to carry all their equipment upstairs b/c our band hall is underground. And they have to load all their stuff and the guards props(I'm in guard, so I feel bad for them) And they run a lot of laps b/c their instructor is fair and decides that since they like to sit at practice when they don't play, then they must have the energy to run a lap after.
My only problem was that they never went outside during summer band for fundamentals.
